氨的拉曼散射研究的结果高达75 GPa的金刚石压砧室的报告。内部和外部模式进行了研究高达30 GPa和内部模式进行了进一步研究高达75 GPa。结果表明，相变在14 GPa和点到另一个在60 GPa，后者的转变导致很可能是一个对称的氢键固体。
Results from a Raman scattering study of ammonia up to 75 GPa in a diamond-anvil cell are reported. Both internal and external modes were investigated up to 30 GPa and internal modes were further examined up to 75 GPa. The results show a phase transformation at 14 GPa and point to another one at 60 GPa, the latter transformation leading very likely to a symmetric H-bonded solid.
